IMPROVEMENT m COR'N-HARVESTERS.

Specification forming part of Letters Patent 0. 189,430, dated April 10,1877 application filed March 24, 1876.

To all whom it may concern Be it known that WB,WILLIAM H. COX and JOSEPHL. Cox, of the city of Milwaukee, in

ments which are used for gathering and husking corn in the field,commonly known as corn-harvesters and our invention consistsin certainnew and improved devices and combination of devices whereby theoperation of pulling the corn from the stalks and removing the husk orshock from the ear is accomplished with greater certainty and with lessinjury to the grain, all as hereinafter more fully set forth.

Figure 1 in the accompanying drawings represents a top elevation of ourinvention. Fig. 2 represents a bottom elevation of our invention. Fig. 3represents a partial view of gearing of rollers. Fig. 4 represents aside elevation of the same.

Similar letters of reference indicate correspondin g parts.

A represents the frame of the machine, and is made of any strong anddurable material suitable for the purpose. B B represent thedriving-wheels of the machine, upon which the frame A is supported. b bare spur-wheels, which are either cast upon or securely bolted to thedrive-wheels B B. c c are pinion-wheels,.

which have a lateral movement upon the axle or shaft d d, and are, atthe pleasure of the operator, thrown in or out of gear with thespur-wheels b b. The pinions c c are attached to the shaft d d, andcommunicate motion to it. e e e e are beveled gear-pinions attached tothe shafts d d. The pinions e e e e are geared with the pinions f f f f,which are attached to the shafts or axles g g g g. The diagonal toothedpinions h h h h are securely attached to the shaftsg g g g, and aregeared with and communicate motion to the pinions j j j j, therebycausing the basking-rollers F F and K K to revolve rapidly. The rollersF F have on their surface spiral-shaped flanges extending from one endto the other, between which flanges are a series of short metallic pins,l l, the object of which, in connection with the spiral-shaped flanges,is to tear the husks from the corn. mm are pinions attached to theshafts g g g g, and are geared with the pinions 'n n. The pinions n nare geared with the pinions 0 o. The pinions 0 0 are attached to theaxle of the serrated circular knives G O, and cause the knives G O torevolve rapidly against the standing corn as the machine is drawnforward. 1) 1a are balance-wheels, and are attached to the shafts d d. qq q q are pulley-wheels, which are attached to the shafts d 01, uponwhich the drive-belts s s are run. D is a drive-wheel, which alsosupports the front end of the machine. It is securely attached to theaxle or shaft N. O O are beveled gear-pinions attached to the axle N,and are geared with the pinions P 1?, thereby communicating motion tothe stud Q. R is a reel mounted upon the stud Q, and revolves with it insuch manner that its arms strike against the standing corn and crowd itback upon the machine simultaneously with its being cut. E E areelevators which convey the husked corn to and deposit it in thecorn-conductor F, and it is thence conveyed into a wagon or otherreceptacle for the purpose. The conductor F is attached to the frame Aat its center by bolt L in such a manner that as one end is raised theother is lowered, by which arrangement it is made to deposit the corn oneither side, as desired. G is a pulley or friction-roller at the lowerend of the elevatorbelt H. The elevator-belt H is made of metallic chainor any other suitable belting material. I I I I are caps or coversattached to the. frame A for the purpose of guiding the corn to andbetween the huskiug-rollers. k k

k k are gathering-arms, which are adjusted to run near the ground, togather up the leaning corn preparatory to its being cut. M, A driversseat may be attached to the ma-' chine between the elevators H H. Theremay also be attached thills or a pole, as required.

The machine is drawn by one or more horses, as required, according tothe condition of the soil or heft of the corn to be cut.

The operation is as follows: The machine is moved forward in thedirection of the arrow, Fig. 1, and operates on two rows of the growingcorn at once. The corn passes in between the gathering-arms k, whichguide the stalks toward the husking-rollers. The reels R raise thestalks and hold them securely against the rollers while the circular saw0 severs them. At the same time the huskingrollers, revolving inwardlyor toward each other, pull the stalk down between them, nip ofl the earstherefrom, and, through the operation of the spirals, flanges, and pins,strip the husk from the ear, leaving the latter free to move along ontothe elevators E, which raise it and deposit it in wagons, or intowhatever receptacle may be adapted to or found most convenient for thepurpose.

It will be seen that the most delicate part of the operation is thesevering of the ear from the stalk, and the stripping ofl' the husk, andtherein lies our improvement. The pins 1 on the flanges of the rollersmaterially aid in quickly removing the husk or shuck, and the cutting ofthe corn-stalk by the circular saws at the right moment prevents allunnecessary drag on the machine, which might otherwise operate to dragthe stalks out by the roots.

We claim as our invention- 1. The spirally-flanged rollers F, havingpins lbetween the flanges, constructed and operating substantially asand for the purpose specified.

2. The combination of the spirally-flanged stripping and hnsking rollersF, having pins between the flanges, with rollers K, and rotary serratedknives or cutters 0, operating simultaneously to cut the corn-stalks,strips them, and husk the ears, substantially as set forth anddescribed.

In testimony that we claim the foregoing as our own we affix oursignature in presence of two witnesses.
